如何将已绑定的游戏账号从旧手机卡更换到新手机卡？

I recently changed my mobile phone card, but how do I change the game's account linked to it?

The first step: make sure you have backed up your game data before changing your mobile phone card.

To do this, you can use the backup function within the game or third-party software.

The second step: after changing your mobile phone card, contact the game customer service and inform them of your new phone number. The customer service will help you update the game account to be associated with your new phone number.

The third step: once connected to the game customer service, you can log in again. During login, you need to verify your identity using your new phone number.

The fourth step: upon logging back into the game, you can restore your game data through the restoration feature within the game or via third-party software.
